Research interests include growth of wide-bandgap (GaN based) semiconductors and their application to blue LEDs as well as laser and high power electronic devices. This research has led to the first U.S. University demonstration of a blue GaN laser diode.
We work at the intersection of design, mechanics, and materials. We develop innovative design concepts and apply non-traditional materials to solve challenging problems in robotics, medicine, and biomechanics.
Professor Petzold's current research focuses on computational methods, mathematical modeling and machine learning, with application to a wide range of problems from systems biology, neuroscience, medicine and engineering.
Work in the Seshadri lab broadly addresses the topic of structure–composition–property relations in crystalline inorganic and hybrid materials, with a focus on magnetic materials and materials for energy conversion and storage.
